Abstract

<p>While immersive VR is one of the useful tools for analyzing human behavior, it has been concerned that human behavior may be different between a VR and a real environment due to the differences in cognitive characteristics. Therefore, to clarify a condition when using VR in analyzing human behavior is reasonable, we investigated the differences between the VR and the real environment in an object searching and manipulating task. The differences were evaluated by the required time to complete the task and questionnaire for the task difficulty. From the results, we realized that using VR is not suitable when the required time for the task completion should be used as an alternative value for the real environment. However, we found there is no problem to use the required time to compare two conditions, such as scoring the performance in robot competitions.</p>
